All of my desktop bookmarks are on mobile, but after resetting my password they won't sync back to my desktop. I can't even access them from my desktop, despite browsing data still being clearly accessible. I have 10 years of bookmarks on my mobile device that for whatever reason now will not transfer to my desktop firefox no matter what I try. Since there's no way to manually export to xml on mobile I have no way of accessing these and I am at risk of losing 10 years of bookmarks, many of which are vital to the work I do.

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

im not very good with tech so ive probably clicked the wrong things, but i cant use my firefox at all anymore. only to search up 'google.com' lol. it opens on the homescreen, but when i want to search anything it always comes out on the screen in the image included. ive been using firefox for a year or so and never had issues. ive tried deleting and reinstalling, restarting my laptop, the whole deal. im on windows 10 but that shouldnt be the issue i imagine. ive asked some friends and they dont understand it either. id love to get some help otherwise i might have to go back to google chrome D:

My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

I have successfully installed Bitdefender Securepass extension on Firefox and enabled it. As far as I know I am not usinf private window but I have no Icon to click on to open

extension as I previously had with Bitdefender Password Manager.

The autostart of the page is attached. It is not possible to disable it. I have tried everything. I have uninstalled firefox and reinstalled it, but unfortunately the page still appears every time I start firefox. Before the update everything was fine, but after the last update it keeps showing me this instead of a blank page with favorites

With the release of Firefox 133, I switched from the add-on Tree-sized tabs to the newly implemented Vertical tabs, and so far I really like the feature. Although, I was wondering if there was a way to reduce the width of the expanded sidebar? Thank you for taking the time to answer my question.

Does anyone know where Mozilla wallpapers are stored? I wanted to set a wallpaper from Mozilla's menu as the desktop wallpaper on my laptop. I looked for hidden files and checked the forums, but I can't find them in the given locations e.g. my profile. Maybe these files are masked somehow. I'm looking for particular wallpaper from the abstraction category (screenshot). Can anyone tell me how to find it?

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Yet another sterling example of why change is usually bad. Why did Firefox, Google and other browsers (though don't know about Duck Duck Go) drop the 100 results per page option? I've always had that enabled and now that it was removed it makes searching extremely tedious and time wasting. Please offer a SIMPLE AND QUICK way to restore this option ASAP. Thank you.

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

I want AI to ALWAYS open when opening the sidepanel. That's why you have a side panel... So how the ... do I STOP Firefox from always opening Bookmarks when the sidepanel is opened?

And No, it doesn't remember last saved choice.

And please fix the ... scaling problem with AI making users manually press UP ARROW to send the message instead of ENTER when the sidepanel is below 40% of the ... screen. This is highly ... annoying!

Recently I haven't been able to sign into Coinbase. When I first try to sign in I just get the spinning circle for a minute or two as seen in the first photo attachment. It then turns into the second image I have attached. It appears to have to do with "human" verification. I set Coinbase as an exception everywhere I can in the setting with no change. This is a recent issue as it only started in September so there a recent change with Firefox. I am able to sign into all other websites without any issue and can sign into Coinbase with every other browser so this is very specific and only applies to Coinbase on Firefox. Why I unable to sign in?

Is it possible to bookmark a particular section of a page, whereas the bookmark will take you to that location?

Textmarker was suggested in another thread, but apparently it is no longer working.
